description: |
Regulator nodes should be named to DSVP and DSVN. The
definition for each of these nodes is defined using the standard
binding for regulators at
Documentation/devicetree/bindings/regulator/regulator.txt.
Datasheet is available at
https://www.richtek.com/assets/product_file/RT4801H/DS4801H-00.pdf

enable-gpios:
description: GPIOs to use to enable DSVP/DSVN regulator.
The first one is ENP to enable DSVP, and second one is ENM to enable DSVN.
Number of GPIO in the array list could be 1 or 2.
If only one gpio is specified, only one gpio used to control ENP/ENM.
Else if both are specified, DSVP/DSVN could be controlled individually.
If this property not specified, treat both as always-on regulators.
Property is deprecated. Use enable-gpios in each regulator.
